The Oklahoma City Fire Department said the earthquake caused them to receive four automatic alarm calls but they have not had to respond to any damage calls in the area.

Saturday afternoon, OCC is telling disposal well operators within 725 square mile area around the location of quake to shut down their wells.

That involves around 37 wells.

Saturday evening, Governor Mary Fallin declared a state of emergency for Pawnee County:

“I’m glad to hear no one was seriously hurt in today’s earthquake and damage appears to be limited. This emergency declaration will start the process to helping individuals, families and businesses impacted by the earthquakes and serves as a precursor to requesting any necessary assistance.

I appreciate the quick response by the Department of Emergency Management and Department of Transportation to assess damage of the affected area and to ensure our state highway and turnpike bridges are safe. And I applaud the Oklahoma Corporation Commission, the state agency tasked with regulating the oil and gas industry, in taking swift action by ordering all disposal wells within a 725-square mile area of today’s earthquake to shut down and working with the U.S. Environmental Protection Agency, which has sole jurisdiction over disposal wells in nearby Osage County.

Information on the earthquake is still being collected and will be reviewed by my coordinating council on seismic activity chaired by Secretary of Energy and Environment Michael Teague, as we continue to move forward to make our state safe.”

I have declared a state of emergency for Pawnee County due to the magnitude 5.6 earthquake that occurred today. . https://t.co/5EnsXuqI8I
